Discussion

Discuss the implications of your findings. Interpret the results and relate them to your objectives.

<<<<<<< HEAD - ZnT8 for control patients … - Missing values for control patients - Missing data for control makes it difficult to determine significant differences between antibody expression for case and control - Results from PCA seems to suggest reducing dimensionality of data by clustering antibodies - No dimensionality reduction suggested from PCA on HLA

Conclusion

Summarize the main points discussed in the presentation. Emphasize the significance of your work and any future directions.
